Obama's Mystery Visit

The above photo from this White House photo gallery shows President Obama stopping by the press section of Air Force One after leaving Baghdad -- while reporters were apparently having a few beers. Just a social visit? What did he say? Did he have a beer?

Update: A reader helps out with some IDs. Left to right, that's Matt Spetalnick of Reuters talking to Obama; Jennifer Loven of the Associated Press in the middle; CBS News producer Jeff Goldman over her left shoulder; then CBS News correspondent Chip Reid. And we think that's Richard Wolf of USA Today in the back.
